LUBBICATING MEANS FOR ROTATORS AND THEIR CASINGS.

Application filed March 15, 1915.

To all whom it may concern Be it known that I, WILLIAM A. GILL, a citizen of the United States, and a resident of Portland, county of Multnomah, and State of Oregon, have inventeda certain new and useful Improvement in Lubricating Means for Rotators and Their Casings, of which the following is a specification. Y

The object of my invention is to provide means which will efficiently lubricate the opposed bearing faces of a rotator and the casing or cylinder in "which it rotates, but not Wastefully apply lubricant to such surfaces.

-My invention further especially concerns rotary valves made of longitudinally divided segments, andin this connection the purpose of my invention isto provide eflicient means for lubricating the bearing faces of the parts while at the same time preventing the lubricant from working into the interior of the valve between the divided faces of the valve segments, for such would cause undue carboni'zation of the interior ofthecombustion' chamber andother ui1- desirable conditions. I

In order that my invention may be understood, it is convenient to refer in the first instance to the accompanying drawings,

which show my invention specifically apent of the United States filed March 2o, 1915, iunder SerialNo. 17,281. Fig. 2 1s a plan section taken on the broken 'line' 22 of Fig. 1, Fig; 3 is aplansection on the broken line 3-3 of Fig. 1; Fig. 4 is a plan section on the broken line H of Fig. 1; Fig. 5 isa sectional detail, taken in a vertical plane, on the line 5 of Fig. 2, showing a part of the hollow valve, and a part of the opposed wall of its casing and against which it bears; Fig. 6 is a diagrammatic view, showing the valve in side elevation and its casing in dotted outlines, and Fig. 7 is a view like Fig. 6, except that the valve is differently positioned.

A brief description of the parts shown in Fig. 1 will be here convenient.

Serial No. 14,623.

a is a valve chamber or cylinder in which rotates a valve 5, made of longitudinally divided, detached segmental sections; the valve being hollow, and the driving fluid being conducted therethrough. On the valve Z) is mounted a coupling 0 of the Oldham type, which serves to connect the valve with a drive-head (Z, also located in the valve chamber above the valve. 6 is a thrust-bearing plate rigidly supported on the frame of the casing. The drive-head 1s madewith a stem d" on the free end of which is secured a nut, not shown, but housed-in the ring f, which is seated on plate 9, by a ball-bearing h, on the upper face of. the thrust bearing plate 6. The latter is made with a chambered portion 0 in which there is mounted on the stem 03 of the drive-head d, a gear 2', meshing with a drive pinion j, and by which means the valve 79 is rotated. The valve casing is provided with-a pipe is, leading from some source of lubricating oil under pressure, to a port Z, leading to the inner face of the valve casing. Each of the segmental parts of the valve, such portions being designated 5, are provided near their upper and lower ends with segmental, circumferential grooves m, n. Said grooves are located medially between the dividing faces of the valveportions and do not extend to such dividing faces, so that no lubricant will be conducted to the dividing faces of the valve parts since, as mentioned in the introduction of this specification, one of the benefits resulting from the lubricating means invented by me is preventing the lubricant from working into the interior of the valve, since such would cause undue carbonization of the interior of the combustion chamber, and itljwould also cause fouling of the spark Each of the valve parts I) is further provided with a series of longitudinally disposed grooves 0, for the. lubricant. These grooves 0, as shown in Figs. 6 and 7, are located medially between the circumferential se mental grooves m, n, but the extremities o the grooves 0 are spaced from the grooves m,n..

The casing a is provided with a connector lubricating groove 29. The connector groove 29 islocated intermediate of the horizontal plane of the circumferential groove m, and said connector groove, 29 is furthermore so disposed and made of such length that its extremities Will extend over the circumferential groove m, and *theupper extremities of the longitudinal g-oove o. The con nector groove 22 .is preferably located helically With respect to the axis of the valve '5; that is to say, said grooveihas an inclination in the direction of the travel of the valve, the purpose of whichistopromote the flow of the lubricant, preventing the latter from dragging. The circumferentiallubricant grooveat the loWer endof the valve parts issupplied with lubricant 1 by the port q-at the lower end of the conduit 1', eXtend ing in the valve casing, Which'conduit intersects the port .Z of the-valve casing, and such conduit is provided at its upper end With a port -s, \WhlCh supplies ilubricant to the exterior of :the: drive head (Z.

t are recesses cut in the meeting 1facesiof the .valveiparts, and provide aniopening in the valve corresponding to the portsof the valve casing, as usual.

a is a closure plate for the topend of the valve chamber.

The parts .notzherein specifically described, are similarltoilike parts descil ihed in' my :said co-pending application for Letters Patent.

As thebalve b rotates, theigrooves m and a Will register With the lubricant ports Z andv g ofrthe casing and lT/Vlllbfi filled With lubricant. As the valve rotates farther, the upper circumferential groovem vwill register with the :upper end of the :connector helical groove 79, and lubricant will flow down the latter. The =further rotation :of the valvewill bringithe upper ends :of the longitudinal grooves 0 into registration with the ilOWBlEGllClOf theconnector groove 49 and lubricant will :fiow down said longitudinal grooves 0. See :Fig. 47. And it is to be noted thatiatano time will lubricant under pressure ibe supplied to the longitudinal grooves 0 while they are passing the :ports of 'the valve casin g.
